Create the Keys for the Server and the
Client

To protect the data transmitted between the server and client, you create
a hashing key and an encryption key. The server uses the hashing key to protect
the integrity of the wanboot program. The server uses
the encryption key to encrypt the configuration and installation data. The
client uses the hashing key to check the integrity of the downloaded wanboot program. The client uses the encryption key to decrypt the data
during the installation.

First, you assume the same user role as the web server user. In this
example, the web server user role is nobody.

wanserver-1# su nobody
Password:

Then, you use the wanbootutil keygen command to create
a master HMAC SHA1 key for wanserver-1.

The previous command creates a HMAC SHA1 hashing key and a 3DES encryption
key for wanclient-1. 192.168.198.0 specifies the subnet
of wanclient-1, and 010003BA152A42 specifies the client
ID of wanclient-1.
